原文:ArcGIS API for Silverlight 当DataGrid选中项时,地图聚焦弹出窗口,并可以播放音频文件 先看效果图,然后上代码: <UserControl x:Class="MapClient.PicMusic" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx
用MPLAB IDE编程时,软件总是弹出一个窗口提示:"the extended cpu mode configuration bit is enabled,but the program that was loaded was not built using extended cpu instructions.therefore,your code may not work properly."怎么办? 在main函数前加一句伪指令:#pragma config XINST=OFF即
